高强度锚杆支护在榆次A矿易碎顶板支护中的应用

摘要

The paper introduces high strength bolt support and analyzes its support principle for broken roofs. The two-year application in Mine A demonstrated: the support could speed up the driving, reduce cost, and improve safety, which was effective and worth spreading.%介绍了高强度锚杆支护技术，分析了易破碎顶板支护原理，该技术在A矿的两年实践表明：高强度锚杆组合配套支护在A矿使用以来，加快了掘进速度、降低了掘进成本、提升了安全保障，效果非常显著，值得推广应用。
